Fuel; Fuel For Petrol Engines; Fuel For Diesel Engines - Opel Automobile Owner's Manual

Permanent deactivation
Permanently deactivate the system
by pressing and holding the E button
on the instrument panel for approx.
3 seconds with the ignition on and
reverse gear engaged. The system is
deactivated and will not operate.
When reverse gear is selected no
acoustic signal will sound, indicating
deactivation.
The function is reactivated by
pressing and holding button E for
approx. 3 seconds.
Fault
If the system detects an operating
fault, a continuous acoustic alarm will
sound for approx. 5 seconds when
selecting reverse gear. Consult
a workshop to have the cause of the
fault remedied.

Fuel

Fuel for petrol engines

Only use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater
than 5 % may only be used if the
vehicle has been specifically
developed and approved for these
fuels.
Use fuel with the recommended
octane rating 3 148. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.

Fuel for diesel engines

Only use diesel fuel that complies
with DIN EN 590. The fuel must have
low sulphur content (max. 50 ppm).
Equivalent standardised fuels with
Driving and operating
a biodiesel (= FAME according to
EN14214) content of max. 10% by
volume (like DIN 51628 or equivalent
standards) may be used.
Do not use marine diesel oils, heating
oils or entirely plant-based diesel
fuels, such as rape seed oil or bio
diesel, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
The flow and filterability of diesel fuels
are temperature-dependent. When
temperatures are low, refuel with
diesel fuel with guaranteed winter
properties.
